About the book
The book intends to present modern technologies involved in welding. The introduction will point out the state of the art in welding technologies, arc physics, and weld pool behavior from the modern point of view, followed by principal requirements in welding quality. Within the topic of automation and control, sensor fusion, control theory involved in welding, measurement techniques systems, and robot usage in welding, which includes off-line programming and vision system and path planning programming will be covered. Modern power source will highlight dynamic characteristics of power sources, and present adaptive control in arc length and many commercial modern power sources offered by the industry: STT, RMD, CMT, pulsed, synergic, etc. by showing their characteristics. The topic hybrid welding processes will present the tendency of using lasers together with many common welding processes in order to improve performance and welding quality. Industry 4.0 technologies applied to welding, additive manufacturing, orbital and underwater welding linked to petroleum industry will be covered within the topic of modern welding applications. Finally, the book will present new tendencies for productivity, performance and weld quality increasement in welding, by using techniques such as artificial intelligence, neural networks, deep learning, data mining and big data.
